Problems solved by technology

This kind of braking method has a slow response and is prone to high temperature after braking. It is not suitable for use in coal mines with high gas and coal dust everywhere. It is also easy to lock the wheels during emergency braking and cause accidents such as derailment. The braking method has the disadvantages of low safety factor and waste of energy

Abstract

The invention relates to an explosion-proof storage battery electric locomotive which is provided with a driving part with simple structure, long service life, high transmission efficiency, low failure rate and small operation noise and a braking part with rapid reaction, high safe factor and energy conservation. The locomotive comprises a carframe, wherein the carframe is provided with an electric part, an explosion-proof storage battery power supply device, the driving part and a mechanically braking part; the driving part comprises a motor; shaft heads at two ends of the driving part are connected with the carframe through a guiding frame and a damping spring; the motor of the driving part comprises a shaft; the shaft is externally and fixedly connected with an inner stator support; the inner stator support is externally and fixedly connected with an inner stator; a shell is arranged outside the shaft in a mode of rotating relative to the shaft; a permanent magnet is fixedly arranged in the shell; the inner stator is corresponding to the permanent magnet and is positioned in the permanent magnet; a power supply cable of the motor is led out from one end of the shaft, the other end of the power supply cable of the motor is connected with speed-regulating IGBT (insulated gate bipolar transistor) modules; and the power supply cable of the motor is connected with the middle three ends of a three-phase bridge circuit composed of the speed regulating IGBT modules.

Description

technical field [0001] The invention relates to an electric locomotive, in particular to an electric locomotive with a flameproof storage battery. Background technique [0002] At present, the traditional explosion-proof battery electric locomotive includes the frame part, the driving part, the braking part, the electrical part, the explosion-proof battery power supply device and other parts, and the driving method is mostly the flameproof DC traction motor through the secondary or primary gear reduction device. The torque is transmitted to the wheels, and the explosion-proof DC traction motor works in the form of series excitation. The DC chopper controller reduces the power supply voltage of the explosion-proof battery to change the speed of the series-excited DC motor, thereby realizing the starting and running of the electric locomotive, etc. control. There are many shortcomings in this driving method, such as complex mechanical structure, large volume, inconvenient dis...
